Calling all nature lovers – join the 2019 City Nature Challenge, a friendly, global competition to see who can make the most observations of nature, find the most species, and engage the most people using the
iNaturalist app. Last year San Francisco swept all three categories, beating 60 cities around the world. Now we need your help to defend our title!
City Nature Challenge will take place in the Presidio the weekend of April 26 to 29 – you’re invited to one of our many bioblitz events where we'll record the wild plants and animals that can be found in this national park. We'll pair volunteers with professional naturalists on a scientific adventure through the park's wildest places. This is fun for the whole family – come on out!
